7 Safety 7 NOTICE! Damage to the device due to missing pipette tips. Use the pipette with fitted pipette tips only. NOTICE! Carry-over, contamination and incorrect dispensing results due to the incorrect use of pipette tips. The pipette tips are for single use only. Prolonged use can have a negative impact on dispensing tasks. Only use the pipette tips once. Do not use autoclaved ep Dualfilter T.I.P.S. for dispensing. NOTICE! Incorrect dispensing volume with special liquids and due to temperature differences. Solutions with physical data very different to that of water or temperature differences between pipette, pipette tip and liquid may result in incorrect dispensing volumes. Avoid temperature differences between the pipette, pipette tip and liquid. NOTICE! Damage to device due to penetration of liquid. Only immerse the pipette tip in the liquid. Do not put the pipette down when the pipette tip is filled. The pipette itself may not come into contact with the liquid.

13 Operation 13 4 Operation 4.1 Setting the volume Setting a small volume Set the volume from a high to a low value. 1. Turn the volume setting ring clockwise. The set volume is shown on the volume display Setting a large volume Set the volume from a high to a low value. 1. Turn the volume setting ring counterclockwise. The set volume is shown on the volume display Reading the set volume The volume is shown on the volume display. The decimal place is under the hyphen. 1. Read the volume from top to bottom. Set volume: 80 μl.

14 14 Operation 4.2 Attaching the pipette tips The pipette tip can be attached by hand or mounted directly from a tip holder (tray) with the pipette. The pipette tips are single-use items. The control button and the trays are color-coded. The color marks the pipette size and the volume of the pipette tip (ept.i.p.s.). 1. Insert the tip cone into the pipette tip using light force. 4.3 Optimum immersion depths Volume Immersion depth 0.1 μl 1 μl 1 mm 1 μl 100 μl 2 3 mm 100 μl 1000 μl 2 4 mm 1 ml 10 ml 3 5 mm

15 Operation Forward pipetting Aspirating liquid Prerequisites The pipette tip has been attached. To ensure maximum precision and accuracy, we recommend initially wetting each new tip by aspirating and dispensing the liquid one to three times. 1. Press down the dispensing button to the first stop. 2. Immerse the pipette tip vertically in the liquid. 3. Maintain the immersion depth and let the dispensing button slide back slowly. Liquid is aspirated into the pipette tip. 4. Wait until the liquid has been aspirated. 5. Remove the pipette tip from the liquid. If necessary, wipe the pipette tip against the tube inner wall Dispensing liquid 1. Place the pipette tip on the tube inner wall at a steep angle. 2. Slowly press down the dispensing button to the first stop. The liquid is dispensed. 3. Wait until the flow of liquid stops. 4. Press down the dispensing button to the second stop. The pipette tip is completely emptied. 5. Hold down the dispensing button and wipe the pipette tip on the tube inner wall Ejecting the pipette tip Press the ejector. The pipette tip is ejected. 4.5 Reverse pipetting An additional volume (blow out) is aspirated when performing reverse pipetting. This can improve dispensing results for viscous or foaming liquids. Volume limits may occur when using filter tips.

16 16 Operation Aspirating liquid 1. Press down the dispensing button to the second stop. 2. Immerse the pipette tip vertically in the liquid. 3. Maintain the immersion depth and let the dispensing button slide back slowly. Liquid is aspirated into the pipette tip. 4. Wait until the liquid has been aspirated. 5. Remove the pipette tip from the liquid. If necessary, wipe the pipette tip against the tube inner wall Dispensing liquid 1. Place the pipette tip on the tube inner wall at a steep angle. 2. Slowly press down the dispensing button to the first stop. The liquid is dispensed. 3. Wait until the flow of liquid stops. 4. Hold down the dispensing button and wipe the pipette tip on the tube inner wall. Residual liquid remains in the pipette tip. During dispensing, the additional volume (blow out) does not belong to the dispensing volume Ejecting the pipette tip 1. Press down the dispensing button to the second stop. The residual liquid is dispensed. The residual liquid can be discarded. 2. Press the ejector. The pipette tip is ejected. 4.6 Storing the pipette The pipette can be stored in a pipette carousel, a wall mount or in horizontal position.

17 Troubleshooting 17 5 Troubleshooting 5.1 Error search Problem Cause Solution The adjustment seal has been removed; the adjustment display has been changed Control button Dispensing The pipette has been adjusted for a different liquid. Problem Cause Solution The dispensing button jams and does not move smoothly. The piston is dirty. The seal is dirty. The seal is defective. The pipette is blocked. Adjust the pipette for the liquid used. Clean the lower part. Replace the protection filter (2.5 ml 10 ml). Problem Cause Solution Liquid is dripping from Pipette tip is loose. Firmly attach the pipette the tip and/or the tip dispensed volume is Deactivate the incorrect. spring-loaded action. Use ept.i.p.s. pipette tips. For 2.5 ml, 5 ml and 10 ml ep Dualfilter T.I.P.S. pipette tips, work without a protection filter in the pipette. Liquid with high vapor pressure and/or different density. Pipetting was too quick. The tip is withdrawn from the liquid too quickly. Liquid aspirated with blow-out and dispensed with blow-out. Wet the tip several times and adjust the pipette for the liquid used. Move the dispensing button slowly. Withdraw the tip slowly from the liquid with a time delay (approx. 3 seconds). Repeat dispensing correctly.

18 18 Troubleshooting Problem Cause Solution Pipette tip Tip cone The piston is contaminated. The tip cone is damaged. The O-rings of the tip cones are damaged. Clean and grease the piston. Replace the lower part or channel. Replace the O-rings (100 μl, 300 μl and 1200 μl multi-channel). Problem Cause Solution Pipette tip is loose. The pipette tip is not compatible. Use ept.i.p.s. pipette tips. Use a suitable size. Higher attachment forces are required. Firmly attach the pipette tip. Deactivate the spring-loaded action. Problem Cause Solution No spring-loaded action of the tip cone. The spring-loaded action is blocked. Use of a 2.5 ml-, 5 ml-,10 ml or 1200 μl pipette. Remove the locking ring (single-channel). Remove the locking clip (multi-channel). The tip cone of these sizes does not have spring-loading action. To prevent dispensing errors, regularly check the precision and accuracy of the pipette. The gravimetric test and the conversion of the measured values for the volume are described in the document Standard operating procedure for manual dispensing systems".
